EYB lamp burnout

[Claudia Mahlman <Claudia_Mahlman@k12bangor.maine.com>]

Hi Everyone,

This has bothered me for years, and I wanted to know if any other school is
experiencing it.

The library distributes lamps for its AV equipment. Since our renovation in
1993, we have experience an excessive burn-out rate for EYB lamps for our
overhead projectors, (mostly  new Bell & Howells, but not exclusively).

I switched to EYB-5 lamps two years ago, but it has not slowed things down.
Changing EYB brands also has not made a difference. The electricians have
checked room outlets and the schools electrical system, but nothing has been
found. I have sent machines out for cleaning and servicing, but that doesn't
seem to improve the situation.

What makes this additional puzzling, is that the old overheads (25-35 years
old) do not burn out as often. I will be purchasing new overhead projectors and
have decided to try a different brand, just to see if that is the problem.

Is anyone else experiencing this problem or is this an isolated problem?

Any ideas about the solution?
